Because of the way we let the actors improvise, it feels like you're watching people react rather than actors reading lines - so I think that's always going to be something I like.

Really it's always things that scare me like loss of control, dealing with the unknown and the unseen... Something that's not supposed to be there and you don't know where it came from, or what it wants from you, or how to defend yourself against it. That's the root of the things I find scary.

Almost any movie, no matter how original, is borrowing from some other movies.

I think the traditional explanation is that demons just find someone, they pick on them and try to break down their spirit so they can... take control of their bodies. Why exactly? I don't know.

In many places around the world, all over the U.S. and Europe there are active nuclear power plants. And for many years during the Cold War the threat of nuclear war was a permanent fear. There's always the concern that human kind is biting off more than they can chew in harnessing nuclear power.

I think the tricky balance, the most important thing more than the horror is to have a compelling story, compelling drama, a show about great characters that you care about and you want to come back every week to see what they're up to.

Usually I don't find gore or slasher films scary. What works for me is the slower build where you are tightening the noose around the situation until you are running out of options and then really have no idea what to do.
